Blue. I'm a romantic, and really, I need some semblance of romance to keep me sane. Otherwise, if I'm cut off from my significant other for even a little while, I get increasingly irritable. Don't get me wrong, I know we both need our own 'me time', but I hate not having chance to contact them.
Its too bad I'm not more Orange, since I love that color. Green I can do without, and as for Gold? To ostentatious for me. I prefer silver.
